United States Patent O 2,772,680 SMOKING DEVICE George W. Rehfeld,Manhattan, Kans. Application April 26, 1952, Serial No. 284,537 2Claims. (Cl. 131-182) This invention relates to tobacco smoking devicesof the type including a tobacco receptacle, and a stem and mouthpieceinterconnected in axial relation therewith. Such smoking devices mayrequire a lter and an insulated tobacco receptacle in order that a cool,clean smoke may be drawn through the` mouthpiece.

In my copending application on Smoking Device, Serlal No. 143,995, nowPatent No. 2,617,427, issued November 11, 1952, I have disclosed atubular stern forming a iilter chamber and which is charged with tobaccofrom a tobacco receptacle so that the tobacco serves as the lteringmaterial. The pipe structure disclosed in my copending applicationoperates satisfactorily, but care is required in packing the filterchamber in order to provide the proper draft and to prevent spilling ofthe tobacco from the filter chamber when the ashes are discharged fromthe tobacco receptacle after the device has been smoked.

It is, therefore, the principal object of the present in- Jention toprovide a smoking device of this character with an improved stem andtobacco receptacle to facilitate filling of the filter chamber so thatspecial care need not be required in order to provide the proper draftand so that the tobacco will not be lost from the filter chamber whenashes are expelled from the tobacco receptacle.

lt is an object of the invention to provide the head of the stem with arestricted passageway that tapers reversely to the exterior taper of thestern head.

It is also an object of the invention to provide a structure whichfacilitates discharge of tobacco from the filter chamber when theVfiltering material must be replaced.

A further object of the invention is to provide a smoking device of thetype described wherein the stem is guided throughout the length thereofwhen the stem is projected into and retracted from the tobaccoreceptacle when packing the tobacco and controlling the burning thereof.

Another object of the invention is to provide a head on the stem whichforms a wedge type seal with the tobacco receptacle and has a forwardlyextending `rim or lip for effecting removal of ashes and caked materialfrom the tobacco receptacle.

A further object of the invention is to provide the head of the stemwitha recess in the forward face to receive the end of a cigarettetherein.

l'n accomplishing these and other objects of the invention hereinafterpointed out, I have provided improved structure, the preferred form ofwhich is illustrated in the accompanying drawing wherein:

Fig. 1 is a perspective view of a smoking device constructed inaccordance with the present invention.

Fig. 2 is an enlarged longitudinal sectional view of the smoking deviceshowing the stem and mouthpiece projected into the tobacco receptacle.

Fig. 7 is a perspective view of the mouthpiece and stem of the deviceshown in Fig. 1, the mouthpiece being shown as removed from the stem.

Referring more in detail to the drawings:

1 designates a smoking device embodying the features of the presentinvention and which includes a substantially elongated cylindricaltobacco receptacle 2, a stem 3 and a mouthpiece 4, all mounted ininterconnected axial alignment. The receptacle 2 includes a wall 5formed of a tubular section of insulating material such as a heatresistant synthetic plastic and having open ends 6 and 7 to receivetherein end members 8 and 9. The end members 8 and 9 are preferablyformed of light-weight material such as aluminum alloy and havecylindrical portions 10 and 11 that are pressed tightly within thetubular section whichy forms the insulating wall 5.

The member 8 has a portion 12 that tapers inwardly toward the axis ofthe members to provide an opening 13 of a diameter adapted to pass thestem 3. The end member 9 has a portion 14 which is open toward the stemend as indicated at 15. It is obvious that the tobacco space 16 in thereceptacle 2 thus formed extends the full material such as aluminumalloy and includes a cylindrical portion 17 having a sliding fit withinthe opening 15. The stem also includes tapered portion 18 correspondingwith the tapering portion 14 of the end member 9 to fit therein andprovide a wedge-tight seal when the stem is in the position as shown inFig. 4.

An insert 19, which may be of non-metallic material, is applied withinthe tapered portion 18 of the stem. The insert 19 has a tapered axialrecess 20. The recess 20 communicates with the relatively small axialsmoke passage 20 which communicates with a recess 21 in the outer end ofthe insert 19. The larger end of the axial recess 20 corresponds withthe inner diameter of the stem while the smaller end is approximatelythe diameter of the smoke passageway 20 to cooperate therewith inproviding for passage of smoke therethrough and to limit spilling oftobacco from the stem into the smoking space that is provided in thesmoke chamber of the tobacco receptacle 2 when the tobacco receptacle isloaded as later described. The insert 19 is pressed into the internaltaper of the stem and gives added wall thickness to provide an annulartamping face 22 for tamping tobacco in the tobacco receptacle. The axialrecess 21 may be used to receive the end of a cigarette so that thesmoking device may be used as a cigarette holder if desired.

The insert 19 may be of a size to permit slight forward projection ofthe stem to provide an annular scraping lip or rim 23 to facilitatedischarge of tobacco from the tobacco chamber.

The opposite end of the stem has a tapered counter- 1 bore 24 tofrictionally receive a tapered end 25 of the Fig. 3 is an end View efthe tobacco charging end of mouthpiece 4. The mouthpiece 4 may besubstantially conventional shape and the end 25 closes the adjacent endof the stem. The stem provides a filter `chamber 26 having its outer enddefined by the insert 19. The filtering material 27 to be contained inthe filter chamber may be loosetobacco (Fig. 4).

` The mouthpiece 4 has a smoke passageway 28 that connects with thefilter chamber 26 and which extends l through the bit 29 of themouthpiece. The bit 29 of the receptacle of the device shown in Fig. l,parts of the i smoking device shown in spaced coaxial relation withportions of the partsbeing broken away and in section to betterillustrate the construction thereof.

` Fig. 6 is a View of the mouthpiece end of the smoking device shown inFig. l.

mouthpiece preferably has a transverse width slightly greater than theinner diameter of the smaller end of the member 9 so that when the stemand mouthpiece are in telescoped relation with respect to the tobaccoreceptacle, the stem and mouthpiece are retained therein but are adaptedto be slid through the tobacco receptacle when pressure is applied inthe longitudinal direction of the mouthpiece to force the side edges 36and 31 of the bit 29 through the smaller end of the tapered portion 1,4,the end member 9 being of suiicient resiliency to allow the slightdistortion necessary to permit the side edges 312 and 31 to slidethrough the small end of the tapered portion 14 when the bit is to bewithdrawn from the tobacco receptacle.

In using the smoking device, the mouthpiece 4 is removed from the stem 3and loose tobacco is inserted into the filter chamber 26 and is packedtherein through the open end from which the mouthpiece was removed. Theinsert 19 at the forward end of `the filter chamber 26 having thetapered recess 2t) therein prevents the tobacco from the dischargingfrom that end of the filter chamber.

The stem may be removed from the tobacco receptacle by sliding the sameforwardly through the open end 13 with sufficient pressure so that theside edges 3@ and 31 of the bit portion 29 of the mouthpiece 4 spreadthe end member 8 sufficiently to allow passage of the mouthpieceportion. After withdrawal of the stem 3 from the receptacle 2, themouthpiece 4 may be removed and the stem tilled with tobacco through theopen end thereof. The mouthpiece 4i is then reapplied and the bit end 290f the mouthpiece is reinserted through the forward end of the tobaccoreceptacle so that the stem and mouthpiece assembly may be slid throughthe tobacco receptacle for seating the taper 18 of the stem in wedgingcontact with the tapered portion 14 of the end member 9.

Tobacco is inserted in the tobacco receptacle through the open end 13after which the charge of tobacco is compressed within that portion ofthe tobacco receptacle that is surrounded by the end member 8. This iseffected by moving the stem assembly forwardly in the tobacco receptaclewith the tamping face 22 pressing against the tobaceo` The stem is thenreturned to again effect a seal of the tapered portion 1S thereof withthe end member 9 which leaves a smoke space 32 between the charge 33 ofthe compressed tobacco within the forward end of the smoking receptacleand the tapered end of the stem (see Fig. 4). The tobacco may then belighted by applying a tiame at the open end 13 and drawing through thesmoke passage 28 of the mouthpiece 4..

After a smoke, the ashes are readily discharged from the end member 8 bypushing the stem 3 forwardly with the face 22 and rim portion 23 thereofpressing the remaining tobacco and ashes through the opening 13. Thetobacco forming the filtering material remains in the iilter chamber 26of the stem and. is not readily displaced therefrom due to the smallpassageway 29. The smoking device may, therefore, be carried in thepocket without ioss of the tobacco from the filter' chamber. Tofacilitate carrying of the smoking device when empty, it may beteiescoped as shown in Fig. 2.

When it is desired to replace the filtering material, the stern andmouthpiece assembly are removed through the end 13 as above described,after which the mouthpiece 4 is withdrawn from the stem 3. The filteringmaterial may then be discharged through that end of the stern by blowingthrough the opening; 2G. The lter chamber of the stem may then berecharged with tobacco, after which the mouthpiece` 4 is again replacedand the assembly is reconnected with the tobacco receptacle Z. Theydevice may be used as a cigarette holder byv pushing the stern throughthe tobacco receptacle into the position shown in Fig. 2. The end of acigarette, may then be inserted within the recess 21, after which thestem is moved retractively with respect to the tube receptacle toenclose the cigarette therein while the cigarette is being smoked.
